Title: Method for detecting position of underground buried pipe
Inventor: ARAMAKI SHIGEAKI
IPC: G01B7/26
Filed: 1994-03-31
Abstract: PURPOSE:To make it possible to specify the position of an underground buried pipe in a state of noncontact by making a signal current flow directly through the underground buried pipe itself and by measuring a magnetic field generated thereby. CONSTITUTION:First, a high-voltage current is once impressed as shown by points A to D by a power source 12. At the outset of the impression, a very large resistance value is brought forth by a high withstand voltage in a joining part and the like and the current hardly flows. When this state continues for some time, however, the resistance value lowers rapidly and the current turns flowing sufficiently. In a stage wherein the resistance value, at least, lowers, a signal current being a high-frequency current is superposed and a magnetic field generated concentrically around a metal pipe 2 and metal pipes 3 and 4 (within a plane perpendicular to a horizontal plane) is measured. Thereby, a depth (h) can be determined. The position of the metal pipe 2 to be determined can be specified from this depth.

Title: Power device
Inventor: KAWADA TOSHIO
IPC: H02M3/155
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To stop switching operation, and to prevent an extraordinary temperature rise of a component, if an oscillation frequency becomes extraordinarily high by a malfunction of an oscillation circuit, by providing a frequency abnormality detector for detecting abnormal oscillation of the oscillation circuit which determines the switching frequency of a stabilized power supply. SOLUTION: If a triangle wave oscillation circuit 1 malfunctions, a triangle wave having an extraordinarily high frequency is outputted from the oscillation circuit 1 to an error detector 2. The triangle wave having the extraordinarily high frequency is compared with the voltage of a capacitor 6 by an operational amplifier 13, and the difference is outputted as a duty ratio to a transistor 3 and a frequency abnormality detector 9. A square wave of the extraordinarily high frequency inputted to the duty stabilizing circuit 10 of the abnormality detector 9 is outputted to an integrating circuit 11. If a voltage inputted to an inverse input terminal of a comparator 12 from the integrating circuit 11 becomes equal to or higher than the voltage of the non-inverse input terminal of the comparator 12, the comparator 12 becomes in an on-state, and stops switching operation.

Title: Division control system for function of data communication terminal equipment
Inventor: KANAMARU HIROSHI
IPC: G06F13/00
Filed: 1990-04-03
Abstract: PURPOSE:To improve the degree of freedom for application and maintenance of a memory and to prevent the deterioration of quality against the extension of a function by providing a means to control the load state of each divided function to a data communication terminal equipment. CONSTITUTION:A function is divided into pieces within a range where these divided functions attain their prescribed roles independently of each other, and the load state of each divided function is controlled to a data communication terminal equipment 12 via a basic control part 12a and an extension control part 12b. If an unloaded function is required, this function is loaded under the control of both parts 12a and 12b. Then the part 12a functions as a loader or a data transfer controller of the part 12b via an extension control protocol given from a host computer 11. Under such conditions, the functions are controlled in division and therefore an occupied area of a memory can be minimized in a working state. Then it is just required to correct or add only the desired function even in a maintenance or function extension state. Therefore other functions are never adversely affected. Thus it is possible to improve the degree of freedom for application and maintenance of the memory and to prevent the deterioration of quality against the extension of a function.

Abstract: PURPOSE:To realize the optimum control, by providing an arithmetic filter, which filters a course signal, in an input stage of an arithmetic part, which calculates an instruction steering angle signal, so that a bad influence of a differentiated rudder by the 1/6 degree resolution of a course to steering is removed. CONSTITUTION:An arithmetic part filter 11, which serves as an arithmetic filter for filtering a course signal psi, always measures a period tn changing in every 1/6 degrees of a live data of the course signal psi. A signal of an estimated course (f) and an estimated turn rate filtering signal are calculated by using a period Tn-1 before change and a sampling period DELTAt in every periods t1, t2.... And the above signals are input to an input filter 5 of an arithmetic part. The signal of the estimated course (f), when the arithmetic filter 11 and the input filter part 5 are jointly used, generates a smooth change as shown in the drawing even when the live data of the course signal psi, while changing by every 1/6 degrees in a stepped state, is input. Consequently, a bad influence, in which large steering is instantaneously performed, can be decreased small.

Title: Treatment of waste combustion gas
Inventor: UEHARA SATORU
IPC: B01D53/81
Filed: 1982-05-27
Abstract: PURPOSE:To reduce the volume of a bag filter and to reduce the driving power of a fan by removing SO2 and soot and dust simultaneously with a fixed bed of an absorbent then passing the treated gas in the direction reverse from the waste combustion gas and releasing the soot and dust thereafter desorbing SO2 with a high temp. gas. CONSTITUTION:A waste combustion gas contg. SO2 and soot and dust is fed to a fixed bed 12 of an adsorbent from a fan 11, whereby SO2 is adsorbed away and at the same time, soot and dust are captured therefrom. Since the fixed bed is used, substantially no fine powder of the adsorbent is generated and the soot and dust remaining in the waste gas are extremely little; therefore, the treated gas is released directly into the atmosphere from a chimney 16. The gas contg. no SO2, soot and dust is fed reverse from the waste combustion gas through a duct 20 by closing a damper 17 and opening a damper 18 to release the captured soot and dust when said gas passes through the bed 12. The gas contg. the soot and dust from the fixed bed is discharged from the chimney through a bag filter 15. A damper 19 is then opened to pass a high temp. gas through a duct 21 to the bed 12 so as to desorb the SO2. The above-mentioned operations are accomplished cyclically in each fixed bed 12.

IPC: B28B1/00
Filed: 1987-04-13
Abstract: PURPOSE:To efficiently obtain a lengthy oxide superconductor by flame-spraying the powder of the specific oxide superconductor to be stuck on a substrate then heat-treating it. CONSTITUTION:The powder of an oxide superconductor expressed by R-A-Cu-O is flame-sprayed and stuck on a substrate then heat-treated. In this chemical formula, R is one or two kinds of La, Y, and A is one or two kinds of Ca, Sr, Ba. No deviation by weight is generated because the sintered and reacted powder is used, thus the constituting material 2 of the oxide superconductor can be uniformly formed on the substrate 1. The crystallization of the material stuck on the substrate is disturbed at the time of the flame spraying or the heat distortion is generated due to the abrupt temperature change, and the superconductivity is deteriorated, thus the annealing heat treatment is performed. The lengthy oxide superconductor can be efficiently and easily obtained accordingly.

Title: Heterojunction field effect transistor
Inventor: HIRAOKA YOSHIKO
IPC: H01L21/338
Filed: 1985-04-26
Abstract: PURPOSE:To obtain a high performance heterojuntion FET, by sequentially laminating high resistance GaAs and n-GaAlAs, which has a broader band gap than that of GaAS, on a p-GaAS substrate. CONSTITUTION:A barrier DELTAE is generated at an interface between a p-GaAs substrate 1 and a high resistance non-added GaAS layer 2, which is to become a channel. When the inpurity concentration of the substrate is 1X10<19>/cm<3>, DELTAE 0.7eV is obtained. The barrier prevents the intrusion of a large amount of electrons into the substrate in order to compensate for the decrease in electron density in a drain beneath a gate electrode when a drain voltage exceeding a drain-current saturated state is applied. The barrier also limits the current to the non-added layer 2 and substantially reduces the electron velocity component in the vertical direction with respect to the substrate 1. As a result, the velocity component in parallel with the substrate is increased, and the saturation value and gm of the drain current are increased. The degree of increase depends on the thickness of the non-added GaAs 2, DELTAE and the length of the gate.
